TAK 250 CDK with f/7.3 focal reducer; fl = 1825 mm.
Modified Hutech Canon 6D, ISO 800, Air ~ 57 F, 0.74 "/pixel.
5 min subs x 11 = 55 min; 5 darks, 3 flats.
Captured with BY-EOS and processed in Images Plus and Picture Window 7.
(The scope only covers an APS-C chip, so with the full size 6D
chip there is a lot of vignetting  around the field edge which flattening has to fix.)
(The pic is cropped.)
